Title: Improvements relating to elements for coupling pipes
Inventor: SERRANO FRANCISCO
IPC: F16L21/02
Filed: 1969-07-23
Abstract: 1,271,855. Pipe connector. COMPAGNIE FRANCAISE DES PETROLES S.A. 23 July, 1969 [22 Nov., 1968], No. 36969/69. Heading F2G. A pipe coupling comprises a tube, a fixed collar secured to the tube, a collar slidable axially along the tube, a sealing ring, and piston and cylinder means whereby the sealing ring may be compressed between the said collars so as to sealingly engage the periphery of a pipe, locking means being provided to retain the movable collar in the ring compressing position. In one embodiment the fixed collar 4 is secured inside tube 3 and is separated from movable collar 6 by gasket 5 fitting over the pipe 25. Projections 7, 10 on collars 6, 9 engage a resilient gasket 8, and a wedge section annulus 14 projects from collar 9 into annular cylinder 11. An annular piston 21 has a plurality of lugs 26 supporting wedges 13. Introduction of pressurized fluid via port 20 forces the piston and collar 9 leftwards compressing gasket 8 and thereby causing collar 6 to press gasket 5 into sealing engagement with pipe 25. Riesilent gasket 8 also sealingly engages the tube 3 and pipe 25 when so compressed. Serrations 29 in wedges 13 are brought to bear on the tube surface thereby locking the collar. To disconnect the joint pressurized fluid introduced via hole 19 slightly recompresses the gasket 8 relieving the radial force on the wedges and allowing piston 21 to be forced leftwards. In another embodiment (Figs. 3 and 4, not shown) the connector comprises a narrow tube with the sealing apparatus mounted externally and adapted for fitting inside the pipes to be joined. In this case the holes 19, 20 can be provided either inside or outside the connector. Pieces 18a, (34a), may be used to facilitate insertion into or around pipes.

Title: Energy transfer machine
IPC: F04D23/00
Filed: 1972-08-08
Abstract: 1387480 Circumferential flow turbines compressors and pumps GARRETT CORP 8 Aug 1972 [9 Aug 1971] 36998/72 Headings F1C and FIT A turbomachine comprises a housing enclosing a toroidal space containing a vaneless stator ring 42 defining an annular flow passage 46 extending about the machine axis 14, rotor blades 60 being disposed in the flow passage such that at least a major part of the inner edge 62 of each blade lies radially inwards of the centroid 98 of the flow passage cross-section and at least a major part of each blade outer edge 64 lies radially outwards of the centroid. The inlet duct 26 to flow passage 46 is oriented such that the absolute velocity of working fluid approaching rotor blades 60 is substantially normal to the direction of motion of the latter. The outlet duct 30 is oriented in alignment with the absolute velocity of working fluid entering the duct. The machine may be a turbine, compressor or pump using gas or liquid as the working fluid, the arrangement described being an air pump e.g. for an automobile emission control system. Air from inlet duct 26 flows in a helical path about annular passage 46, thus passing through rotor blades 60 several times in a radially inwards or outwards direction before leaving through outlet duct 30 at higher pressure. Ducts 26 and 30 are separated by a block 100 integrally formed with stator ring 42 and having an arcuate recess to permit passage of rotor blades 60, the base of the recess being flush with ring face 74 with which the blade tips sealingly co-operate. The machine housing is formed by end members 16 and 18 bolted together and between which is sandwiched intermediate member 32. End member 16 supports stator ring 42 via studs 44 and rotor shaft 22 via bearings 24. In the arrangement shown flow passage 46 is of constant cross-section throughout its circumferential extent but in modifications Figs.9 to 13 (not shown) the cross-section decreases from inlet to outlet by varying the shape of stator ring 42 and/or that of the housing members. In a further modification Figs.14 to 18 (not shown) the stator ring and intermediate housing member are integrally cast, the air inlet duct is of altered shape including flow dividing partitions (190), and a centrifugal dirt separator (194) is provided on the rotor shaft.

Title: Solvent extraction of copper
IPC: C22B15/00
Filed: 1974-08-23
Abstract: 1470876 Copper recovery ISC SMELTING Ltd 24 July 1975 [23 Aug 1974] 37096/74 Addition to 1399281 Heading C1A Aqueous ammoniacal leach solutions containing Zn and/or Pb ion impurities and resulting from the leaching of copper dross are treated to recover dissolved copper values by contacting the solution with a copper selective organic solvent, e.g. LIX 64N or LIX 65N (Registered Trade Marks) in kerosene, to saturate the organic phase with copper followed by separating the loaded organic phase and aqueous phase and then diluting the copper concentration in the organic solvent, e.g. by mixing with fresh organic solvent or recycled copper-stripped solvent, and washing the diluted organic phase with weak aqueous acid such as aqueous H 2 SO 4  and thence stripping the copper from the organic phase with a strong aqueous acid, e.g. aqueous sulphuric acid, to give an aqueous copper salt solution. Saturation loading of the solvent with copper results in a low zinc impurity loading while the dilution step prevents formation of the intermediate phase usually encountered in saturation loading at the organic-aqueous interface and excessive transfer of copper from the organic phase during the weak aqueous acid wash. The wash step removes any remaining co-extracted zinc, lead or ammonium ions from the loaded organic phase.
Patent GB-636123-A (GB)
Title: Improvements in and relating to gyroscope erecting devices
IPC: G01C19/44
Filed: 1946-12-17
Abstract: 636,123. Gyroscopic apparatus. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 17, 1946, No. 37126. Convention date, Dec. 22, 1945. [Class 97 (iii)] The magnetic member of an eddy current erecting means for a gyro-vertical comprises a plurality of permanent magnets so positioned on the magnet member that, on relative movement of the magnet and conductor member, there is a sequential overlap of the poles of the magnet and the conductor member, whereby the erecting torque is maintained over an extended range of relative displacement. Preferably the magnets are so arranged and positioned as to obtain an erecting torque which varies with displacement in accordance with predetermined characteristics. As shown in Fig. 2, an extension 10 of the shaft supporting the rotor 1, carries for rotation therewith a magnet member 7 comprising a frusto-conically shaped base-portion 9 on which are mounted a plurality of rod-shaped permanent magnets 11, 12 whose lower ends project downwardly to form salient pole-pieces and which are held in position by a magnetic back-plate 13. The magnets 11, 12 are arranged in circles of different diameters, the circles being concentric with the axis of rotation of the member 7 and their rotating downwardly-extending magnetic field co-operates with a eddy current disc 8 of copper or aluminium which is pendulously mounted on a bail 14 by an adjusting screw 16 and a locking screw 15. The gyro axis is erected to a small inclination to the vertical by selecting the screw 15 of proper weight so that the disc 8 hangs out of the vertical by the required angle. As shown in Fig. 6, the erection torque due to magnets 11, curve E, and to magnets 12, curve F, combine to give a resultant curve G which may be adjusted to approximate to the curve D which shows the erection torque required for complete elimination of the turn error at all speeds for one predetermined rate of turn. The magnet member may be stationary and the eddy current disc rotated or alternatively the magnet member may be pendulous and the eddy current disc mounted on the gyro. The Specification as open to inspection under Sect. 91 describes also an erecting means wherein the magnet member is pendulously mounted and the eddy current disc which is mounted for rotation on the rotor spindle comprises a plurality of conductor rings so dimensioned and located as to give the required erection characteristics. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in the packaging of articles
Inventor: CURTIS SIDNEY
IPC: B65B11/28
Filed: 1954-12-23
Abstract: 768,862. Wrapping-machines. ROSE BROS. (GAINSBOROUGH), Ltd. Dec. 1, 1955 [Dec. 23, 1954], No. 37184/54. Class 94(1). In a wrapping machine cylindrical plastic articles, e.g. toffees, are cut in succession from a continuous rope, wrapped individually at a first wrapping station and transferred to a collecting station where they are assembled end-to-end to form a batch. The latter is then transferred to a second wrapping station where it is wrapped to form a cylindrical package. A cylindrical rope of toffee 11 is fed horizontally by rollers 12 towards a pocketed transfer wheel 13 which is rotated intermittently by Geneva mechanism 16 to bring each pocket 14 in turn into position to receive the end portion of the rope which is then severed by a rotary knife 17 leaving a toffee 18 in the pocket. The wheel is then rotated to carry the toffee between guide plates 21, 22 into position adjacent a brush folding box 19, a wrapper 23 is fed between the wheel and box and the toffee and wrapper are moved through the box into a pocket 24 of a second wheel 26 by co-operating plungers 27, 28, thus folding the wrapper about the forward end and cylindrical periphery of the toffee. The extending portions of the wrapper are then folded on to the rear end of the toffee by reciprocating folders 29 and the wheel 26 is rotated by Geneva mechanism 31 to carry the wrapped toffee between guide plates 32, 33 to a collecting station where it is thrust by a plunger 37 into a waiting pocket 36 of a collecting wheel 34. Each pocket 36 is wide enough to accommodate ten wrapped toffees and after this number have been fed into the pocket to form a batch, the wheel 34 is rotated by Geneva mechanism 38 to carry the batch between guide plates 40 to a position adjacent a conveyer 39. The batch is then ejected from the pocket by a plunger 43 on to a support 42 where it is engaged by grippers 44 and inserted between supports 41 on the conveyer which transports it to a position opposite an intermittently-rotatable wrapping wheel 46. A composite wrapper is fed between the conveyer 39 and a pocket 48 of the wheel 46 so that it is folded about the batch as the latter is thrust into the pocket by a reciprocating pusher 47, the folding operations being completed during subsequent movements of the wheel. The wrapper may consist of one or more inner layers of waxed paper or foil, end portions of which are folded on to the ends of the batch, and an outer label of slightly less width than the length of the batch which is folded to form a tube.

Title: Improvements relating to borehole drilling
Inventor: GASKELL THOMAS FROHOCK
IPC: E21B7/04
Filed: 1958-11-19
Abstract: 867,025. Drilling oil wells. BRITISH PETROLEUM CO. Ltd., and GASKELL, T. F. Oct., 30 1959 [Nov. 19, 1958], No. 37221/58. Class 85. In the drilling of a bore hole with a drill which rotates relatively to a drill pipe and is connected to the drill pipe by a universal joint, deviations of the drilling line from the desired line are detected by means which are located near the drill and cause a correcting force to be applied between the drill and drill pipe. The drill may be driven by a turbo-drill assembly 3 screwed on to a sleeve 4 having a universal joint suspension 6 within a casing 5, so that the drill is freely movable, to a small extent, out of coaxial alignment with the drill pipe, by the selective activation of three hydraulic cylinders 12 set at 120 degrees around the axis. The hydraulic pressure is obtained from an oil pump 18, driven from the turbodrill by a shaft 20, having a suction connection 24 with an oil reservoir 23 and a discharge pipe 25 running axially to a filter 27 and to a manifold 28 supplying the cylinders 12. An excess pressure valve 26 returns oil to the reservoir, and an accumulator may be provided in the oil line. The cylinders 12 have pistons 11 attached to the upper end of the sleeve 4, the oil pressure being admitted to one or both sides of each of the pistons by electro-hydraulic servo valves 16. The oil admission and exhaust pipes 29, 30 project radially from the pressure pipe 25 and an exhaust pipe 32 surrounding it to form an annular exhaust passage; the pipes 29, 30 being slidable in the servo valves 16. The detector is a pendulum 39 suspended by a ball joint 40 from a housing 35 containing an electrical power supply. The pendulum 39 is constrained to small movements by a stop 41, these movements moving the stylus 44 of each of three potentiometers 43, one for each cylinder 12. The potentiometers are connected to the power supply and thus each feed a signal to the associated servo valve 16. When the drill is in correct alignment, the servo valves act to maintain full pressure on both sides of all the pistons 11, thus locking the drill in its correct position. When deviation occurs, the pendulum operates the servo valves to apply the restoring force. The pendulum may act on the potentiometers through a control arm which may be preset to hold the drill to a desired off-vertical drilling direction. According to the Provisional Specification, the inclinometer signals may be transmitted to the surface, and electrical or hydraulic impulses are sent from the surface to correct the drill.

Dec. 31, 1934, No. 37403. [Class 39 (iii)] In apparatus for waving hair in which the heat is generated by passing an electric current through an absorbent material soaked in an electrolyte, as described in Specifications 433,290, 433,351, and 450,084, [Group XIV], and in which a part or the whole of the vapour is generated either within a hollow rod on which the hair is wound, or in the tress itself, an outer covering of pliable metal or metal foil, serving as one of the electrodes, is tightly wrapped round the coiled tress so as to allow exit of vapour only at the end away from the scalp, Fig. 1, shows an arrangement in which electrolysis takes place and vapours generated both within a hollow perforated rod 6 on which the hair is wound and in a layer of absorbent material 16 surrounding the tress. The rod 6 contains absorbent material 12 wrapped on a wire 13 forming one electrode. The material 16 is enclosed between an inner perforated sheet of metal foil 17 and an outer imperforate sheet 19. The device is held in an insulating head 21 having spring slips 37 making contact with the sheet 19 and the wire 13 and clips 32 making contact with the rod 6, so that the two lots of absorbent material are connected in parallel, in a modification they are connected in series. The clips are retained by a removable hollow plug, into which the rod 6 also fits. To replenish the electrolyte in the rod 6, so as to prolong the time of treatment, there is provided a compressible reservoir 43 opening above the upper end of the rod. Modifications are described in which the reservoir 43 is replaced by a wick of absorbent material, or in which the electrode 13 and absorbent material 12 can be removed from the rod, soaked in electrolyte, and replaced without disturbing the hair. The lower part 20 of this layer 16 may be made thicker than the upper as shown in Fig. 8 and the lower edge of the layer may be wrapped in a fold of impervious material 21, or of highly absorbent material, to prevent hot liquid from running down to the scalp. To ensure further that the lower part of the tress is more intensely heated than the upper the perforations in the layer 17 and the rod 6 may be larger or more closely spaced in the lower portion. Modifications are described in which the rod is solid, the electrolysis taking place in the hair itself.

Abstract: 1,114,336. Anodic oxide capacitors. GENERAL ELECTRIC CO. 23 Aug., 1966 [24 Sept., 1965], No. 37706/66. Heading H1M. In manufacturing a capacitor wherein the dielectric is an anodically formed oxide layer on an etched valve metal such as aluminium, tantalum, niobium, titanium-zirconium alloy or titanium-molybdenum alloy, the counter electrode is deposited by decomposition from an organo-metallic compound. The first electrode may be a foil or preferably a coiled wire. The anodized electrode is exposed to the vapour of e.g. nickel, iron, copper or cobalt carbonyl in a heated chamber which is then further heated to above the decomposition temperature of the carbonyl. The carbonyl may be vaporized within the chamber or conducted thereto by means of a carrier gas. Alternatively the anodized electrode may be treated with the carbonyl in liquid form. Instead of heating the chamber to above the decomposition temperature, a current may be passed through the electrode being treated.

Abstract: 1492487 Aircraft brake flaps MESSERSCHMITT - BOLKOW - BLOHM GmbH 15 Sept 1975 [17 Sept 1974 4 July 1975] 37886/75 Heading B7G An aircraft brake flap is hydraulically or pneumatically operated in such a manner that the angle of extension of the flap is dependent on the aerodynamic force acting on the flap. The flap is connected to the piston 7 of a jack, and the angle of extension α of the flap is transmitted to a spool valve 13 through a coupling 14, 15. The spool valve is disposed in a line 12 which joins the fluid feed line 9, downstream of a restrictor 10, to the fluid return line 11. The extent to which the spool valve is opened is governed by the flap extension, and equilibrium is obtained when the flap takes up a particular angle which results in a balancing of the aerodynamic force and the fluid force acting on the piston. Several alternative methods of controlling the fluid pressure acting on the piston in accordance with the brake flap angle of extension are disclosed, Figs. 3 to 8 (not shown).
